Double - Triple title

Hi Support,
I hope you are well. My site shows at the moment triple h1 titles for some pages: http://krbschoolofenglish.com/wp/corsi-inglese-pet-fce-ielts-garbagnate/corso-esame-ielts-garbagnate/
title: CORSO ESAME IELTS
How can I have only 1 (only the 1 on the header)?

On some other pages I have 2: http://krbschoolofenglish.com/wp/about-us-2/
thanks a lot

Hello there,

I hope you are doing well today.

You can use the following CSS code to remove the titles by going to Appearance > Customize > Additional CSS and pasting it there.

/*Remove titles*/
#blog .blog-post .blog-post-title {
    display: none;
}

.markup-format h1 {
    display: none;
}

Best Regards,
Support
